[RE-wrenches] Kohler generator 1/2 voltage

[glenn.burt at glbcc.com]

I had a similar issue with an On an off grid genny earlier this year. The customer had a local On an tech come out and they replaced the voltage regulator board and cleared up the issue.They also said these regulator boards for the older gennies were getting hard to find, so just another thing for a customer to consider.GlennSent from my 'smart' phone so please excuse spelling and typos.------ Original message------From: Kirk HeranderDate: Thu, Nov 8, 2018 4:17 PMTo: re-wrenches at lists.re-wrenches.org;Cc: Subject:[RE-wrenches] Kohler generator 1/2 voltageHello,
I got called in to debug an old off grid system with a Kohler 8.5 RES generator. Across L1-L2 is 120vac. From both L1 & L2 to common gnd/neutral is 60v. I verified the windings are connected for 120/240 operation(in series with center tap for G/N). These voltages are the same on the genny side of its breaker when turned off (no inverter connection). I am having trouble envisioning a scenario of mis-wiring if indeed each one of the windings is producing 120 VAC. Seems odd to me that a bad regulator would cause this, but who knows. Alternator? Ideas? Thanks.
